What is the problem of data response in the case of vuex multi-module?

the project has multiple modules: home module, login module, etc. Each module has its own data.
I get the data from vux on other pages and assign variables to the current page.

this.userinfo = this.$store.state.login;//vuex
this.userinfo = this.$store.state.login.userinfo;//

the following is OK. I've always been the one below. What do you mean by "no"?

MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1e4f765-45027.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
